It triggers behavioural, physiological and immunological changes that generate negative consequences on the health of both ewes and lambs, as well as on the growth of the lambs, rising animal welfare concerns. In addition, after weaning, the ewe and the lamb decrease their time lying down, grazing and ruminating (Figures 2, 3).

I weaned my lambs 3 weeks ago, can I assume the ewes have dried up enough to now share a field with the lambs again? P.O. Early weaning | Winter 2019 | Sheep Notes newsletter | Newsletters Progesterone administration reduces the behavioural response of ewes at weaning. As the greater milk production occurs in the first month, the amount of milk is enough for the normal development of the lambs and to produce commercial milk (Sevi et al., 2009). Ewes and lambs weaned by fence-line separation vocalise more and eat less than those weaned abruptly (Orgeur et al., 1999). Behav. Anim. These types of weaning can be done abruptly, progressively, or in steps (see section WEANING METHODS). Behav. Although the age at artificial weaning appears to be more challenging for the lambs than for the ewes, to the best of our knowledge, there is no published article studying the stress response of ewes according to lambs' weaning age. Res. Sci. Czech J. Anim. Figure 2. The effects of alternative weaning methods on behaviour in beef calves.

Consequently, spring-born lambs are heavier before and after weaning than autumn-born lambs (Menant et al., 2022). "On The Lam" - Meaning & Origin (12 Helpful Examples) - Grammarhow doi: 10.1016/j.smallrumres.2006.07.010. Physiol. This can be accomplished by removing lambs from their mothers' pen but maintaining their contact through wire-fence, covering the udder, or using nose flaps to avoid suckling for a limited period before ewe-lamb separation. Appl. Maldonado, A., Orihuela, A., Aguirre, V., Vzquez, R., and Flores-Prez, I. Anim. When a ewe is giving birth, she makes these special noises that sound a bit like snoring. Two-steps weaning consists of limiting the access to the mothers' udder before definitive ewe-lamb separation, either continuously or temporarily. Busnel (New York, NY: Academic Press), 75119. During these periods of contact, lambs suckle ad libitum and interact freely with their mother. doi: 10.1002/dev.20024, Vatankhah, M., Talebi, M. A., and Zamani, F. (2012). Psychobiol. The response to progressive weaning likely differs according to the age at which it begins, as progressive weaning from 5 to 10 d of age induces behavioural, endocrine, and immune disturbances in lambs (Sevi et al., 2003). Sci. Type of weaning more commonly applied according to the age of lambs and sheep production systems. How to Use On the lam Correctly - GRAMMARIST J. Anim. Several factors may influence the strength of the attachment in lambs [e.g., sex, with female lambs showing a stronger attachment (Gaudin et al., 2015), birthweight (Menant et al., 2020)], and in ewes [e.g., parity (Dwyer and Lawrence, 2000; Freitas-de-Melo et al., 2021a), breed (Lawrence and Dwyer, 1999; Pickup and Dwyer, 2011), and temperament (Catherine and Alistair, 2000)]. The first thing you should do is get an orphaned lamb dry and warm immediately. Early weaning in bighorn sheep, Ovis canadensis affects growth of males but not of females. Housing Housing can have a huge impact on lamb health. 2, 281. doi: 10.1016/0168-1591(95)92372-Z, Zhang, Q., Chong, L., Xiaolin, N., Zhian, Z., Fadi, L., and Fei, L. (2018). P. Jewell, C. Milner, J. Boyd (London: Athlone Press), 131159. Lambs born in March/April would normally be sold in the fall when prices are traditionally the lowest. Moreover, as social demands require a sustained decrease of practises that might affect animal welfare, the development of new strategies can impact not only in productivity, but also in the future sustainability of the productive systems. A delay in this process has negative consequences on lambs' metabolic and hormonal status (Alexander et al., 1986; Nowak et al., 1997, 2021). Food restriction during gestation negatively affects the lambs' birth weight, the mother-lamb bond at lambing (Dwyer et al., 2003; Freitas-de-Melo et al., 2015a), and reduces the number of rejecting behaviours towards alien lambs by selective mothers (Freitas-de-Melo et al., 2018b). Sci. Anim. Progesterona y respuesta de estrs: mecanismos de accin y sus repercusiones en rumiantes domsticos. Agr. Mex. Behav. Dev. This delay in growth may be a consequence of a bad adaptation of the digestive system to the acute feeding changes, the reduced immune status, the increased susceptibility to gastrointestinal parasites, and the energy dispended in the display of costly behavioural responses. Therefore, this treatment can also potentially reduce susceptibility to diseases of ewes after weaning. (2011). Behav. Effect of weaning system on commercial milk production and lamb growth of East Friesian dairy sheep. 14, 249264. Sheep weaning best practice | Agriculture and Food The sucking behaviour of triplet, twin and single lambs at pasture. Moreover, the administration of starter feed in weaned lambs at 10 d of age stimulates the development of ruminal epithelia, accelerating the cell cycle, inhibiting apoptosis in the rumen epithelium, and promoting the uptake of volatile fatty acids (Sun et al., 2018). Male and female lambs have different productive goals after weaning, as in general male lambs are finished for slaughter, and female lambs replace breeding animals (Kenyon and Cranston, 2017). 194, 362370. doi: 10.1016/j.applanim.2018.08.022, Dhaoui, A., Chniter, M., Lvy, F., Nowak, R., and Hammadi, M. (2020). Furthermore, faecal worm egg counts are lower in supplemented-weaned lambs than unsupplemented lambs (Shaw et al., 1995), probably because supplemented-weaned lambs are less exposed to parasites, improving the health status of lambs. 236, 105256. doi: 10.1016/j.applanim.2021.105256, Ungerfeld, R., and Snchez-Dvila, F. (2012). At 1 week before the first expected lambing date (day 138 after the ram is introduced to the breeding flock), ewes should be observed every 4 to 6 hours. Some responses are reported only in female lambs, such as an increase in albumin concentration (Freitas-de-Melo and Ungerfeld, 2020). Behav. Regardless of lamb's age at weaning, the most frequently used weaning method is abrupt separation (Freitas-de-Melo and Ungerfeld, 2016a), perhaps because sheep farmers can easily apply it. The idiom is on the lam, not on the lamb. Artificial weaning in sheep: consequences on behavioural, hormonal and immuno-pathological indicators of welfare. The effect of a gradual separation from the mother on later behavioral, immune and endocrine alterations in artificially reared lambs. 53, 2836. Anim. Some examples are inducing ewes into oestrus on the day of separation (Prez-Len et al., 2006), the presence of conspecifics or humans with a close emotional bond (Barton, 1983a,b; Carbajal and Orihuela, 2001), applying positive stimulus as stroking (Pascual-Alonso et al., 2015), or pharmacological treatments to decrease the stress perception, as progesterone treatments (Freitas-de-Melo et al., 2013; Freitas-de-Melo and Ungerfeld, 2016b). Understanding how these factors affect the weaning response is essential when adapting managements around weaning. This method is based on some early studies (Owen et al., 1969a,b) that concluded that the transition from the initial to substantial consumption of solid food is strongly influenced by milk intake.

Anim. Sci. The sex of the offspring affects the lamb and ewe responses to abrupt weaning. The inconsistency between the results of these studies could be due to the difference in the time taken for ewes to perceive the absence of their lambs. Altogether, these stressors trigger strong responses in both members of the dyad, which generally negatively affect their physiological and health status, constituting a significant welfare issue. Interestingly, there was no difference in total commercial milk produced by ewes abruptly weaned from their lambs 24 h postpartum and ewes maintained in the mixed regime (McKusick et al., 2001), probably because the contact with the lamb stimulates a greater milk yield. Psycological consequences of two different weaning methods in sheep. Livest. Ewes emit bleats within 3 h before and after parturition (Sbe et al., 2007), and by 48 h after birth, the lambs can identify the low-pitched bleats of their dam (Sbe et al., 2010). The critical period in the attachment of lambs and ewes. Although weaning is one of the most stressful events in farm animals for both, mothers and offspring, there are important gaps in the knowledge required to decrease the negative concerns of a widely used handling. However, there are some studies aiming to handle the weaning promoting animal welfare. The condition is characterised by sudden death and occurs most commonly when weaned lambs have been fed fast-growing lush pasture for a period of three weeks or more. Behavioral and physiological responses to early weaning in ewes and their single or twin lambs.

The ewes' interest in their lambs is greater after birth, and declines gradually along the lactation period, as the lambs gain social and nutritional independence (Weary et al., 2008; Maldonado et al., 2015). Ewes and lambs increase the number of vocalisations, and the frequencies of standing up and walking, as well as pacing (when animals walk at a distance of 1 to 2 m parallel to the fence, modifying the direction of back and forth repeatedly) (Alexander, 1977; Freitas-de-Melo et al., 2013, 2019) (Figure 1).
